title: Methyl 2-(5-chloro-1-methyl-2-oxo-2,3-di-hydro-1H-indol-3-ylidene)acetate.
abstract: The title compound, C12H10ClNO3, the indoline ring system is essentially planar, with a maximum deviation of 0.009 Å for the N atom. The indoline ring and acetate group are essentially coplanar, with a maximum deviation of 0.086 Å for the O atom. The mean plane through the methoxy-carbonyl-methyl group forms a dihedral angle of 3.68 (5)° with the plane of the indoline ring system. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen-bond inter-action. In the crystal, π-π stacking inter-actions [centroid-centroid distance = 3.7677 (8) Å] occur between benzene rings, forming a chain running along the c-axis direction.
